Bricked A501 and no CPUID

Hi guys!

I have a problem with my A501 with ICS! I watched a movie when it crashed and was unable to boot again. Then it booted into recovery mode which terminated without any problems.
When i boot my tab now it shows the message "Boot verified failed ...". Then i tried to downgrade to "Acer_A501_1.309.02_COM_GEN1" using update.zip but the problem stays the same.

My BIG problem is that i don't have the CPUID or a backup and never connected the tab in apx mode to get it with USBDeview.

Is there an other possibility to get the CPUID or to flash a ROM using update.zip method?

Tab should go in apx mode when holding reset and then while holding reset press power button for about 4 seconds. Then release power button and then reset button. Then power button should light up white while display stays dead.

Then you are on apx mode.

I used open suse to try this method out.

In the xda thread is written that you must install some additional software packages, don't forget that. And then it doesn't work on every PC. I have to use my notebook for this method to work because it doesn't work on my PC.
Seems to depend on mainboard's chipset.

Tab should go in apx mode when holding reset and then while holding reset press power button for about 4 seconds. Then release power button and then reset button. Then power button should light up white while display stays dead.

This is exactly what i did. Further i installed all packages listed in the XDA thread and was able to compile the apx program without any compiler/linker error.

Later this evening i will try out your seggestion to use a different computer/laptop.

UPDATE: I tried two different laptops but had no luck. I got always the same error message "Error: Failed to open device!"

Is the device ID 0955:7820 correct for an A501 in APX mode?

UPDATE 2: I took a look at the apx tools source code and saw that it is the correct id, as the tool tries to open a device with the same ID.

Does anybody have a clue what is going wrong?

EDIT: I finally got my CPUID :-)!!! I did not know that i have to run the apx program as root....
